Reportlab.platypus. Calculating true three-fold PDF in Python. I created a three-column PDF format using frames and reportlab in the article Multi-column PDFs.
However, the document I used as an example was meant to be folded, and that was not a true three-fold layout. All of the columns were the same width and they were distributed evenly within the available printing area of the page. In order to make it truly foldable, the borders between each frame need to be distributed evenly across the entire paper width. This means that, unless there are only two columns, the outer frames need to be sized differently than the inner frames. I divided this into four basic steps: Add an inner margin size.Set the frame width to be the first fold point, minus the inner margin size.Adjust the first and last frame appropriately.Draw guides for folding. I modified the frame code to handle steps one through three: [toggle code] Drawing a fold guide We can make it easier for people to fold the sheet by adding a dashed vertical line exactly at the fold.

Every page should look exactly the same on any platform, regardless of user settings. If a user were to view a certain web page on my computer and then switch the resolution, the change could be quite significant. Likewise, if a user viewed a web page or some other sort of document on Windows and then switched to Linux, things might also look very different. This is fine for a lot of things, but when pages need to be formatted in a precise way, as in books or user manuals, it becomes a problem. It is, however, a problem that can easily be solved by creating PDF documents for things like these. PDF documents are fairly easy to create today.
